VRE3025BS

The VRE3025BS Voltage Reference from Texas Instruments is a single-channel, low-jitter, low-power voltage reference that provides a precision voltage reference for precision applications. It has a wide range of applications, including microcontrollers, converters, and analog-to-digital converters (ADCs). The VRE3025BS is a versatile, low-power voltage reference, enabling precision voltage reference designs with a number of features and benefits.

Application Field

The VRE3025BS is part of the popular family of voltage references from Texas Instruments and it is a solid-state, programmable voltage reference. It can be used in a wide range of applications including microcontrollers, converters, and ADCs, providing a precision voltage reference for performance-critical applications. For example, the VRE3025BS can be used in microcontrollers to provide a stable reference for the input signal for ADC or DAC. The device can also be used in power supplies or converters to provide an adjustable voltage reference for the voltage regulator and for monitoring its output. Additionally, the device can also be used in RF switches or antenna systems as a voltage reference for signal level control and measurement.

Working Principle

The VRE3025BS operates as a low-power voltage reference in two basic operating modes. The first mode is the “closed-loop” mode, where the output voltage is regulated to a specific, user-defined level by an internal feedback circuit. The second mode is the “open-loop” mode, where the output voltage is directly proportional to the input voltage. The VRE3025BS is a linear voltage device; this means that the output voltage is a linear function of the input voltage. The output voltage is set by a potentiometer and varies in small increments as the input voltage is adjusted.

The VRE3025BS also has two internal resistors for current limiting and protection. The first resistor is a series resistor that limits the maximum current that can be drawn. The second resistor is a shunt resistor that provides protection against over-voltage or “crowbar” conditions. The shunt resistor also limits the output current to a safe level even in the event of an overload.

In addition to the closed-loop and open-loop modes, the VRE3025BS also has a number of other features, including an on-chip temperature-compensated trim circuitry and an adjustable-gain output amplifier. These features allow users to optimize the output voltage accuracy and performance over temperature and other environmental conditions.
